Perplexity Comet
Perplexity's agentic AI browser — free on desktop and mobile.
About
Comet is Perplexity's agentic AI browser: the agent drives the browser — multi-tab task automation, form filling, research — across macOS, Windows, iOS, and Android.
Fully free since March 18, 2026; Comet Plus $5/mo for premium publisher content (bundled with Perplexity Pro/Max). Perplexity raised $200M for Comet in June 2026. Caveat: prompt injection is the category risk — CometJacking was demonstrated and patched.
